Sodium hydroxide is used in the production of paper, soap, dyes and rayon, metal smelting, petroleum refining, cotton fabric finishing, purification of coal tar products, food processing, wood processing and machinery industry. Chemical experiment: it can be used as a chemical experiment. In addition to being used as reagent, it can also be used as alkaline desiccant because of its strong water absorption and deliquescence.

也可以吸收酸性氣體(如在硫在氧氣中燃燒的實驗中，氫氧化鈉溶液可裝入瓶中吸收有毒的二氧化硫);氫氧化鈉在國民經(jīng)濟中有廣泛應(yīng)用，許多工業(yè)部門都需要氫氧化鈉。使用時氫氧化鈉多的部門是化學(xué)藥品的制造，其次是造紙、煉鋁、煉鎢、人造絲、人造棉和肥皂制造業(yè)。

It can also absorb acid gas (for example, in the experiment of sulfur burning in oxygen, sodium hydroxide solution can be put into a bottle to absorb toxic sulfur dioxide); Sodium hydroxide is widely used in the national economy, and many industrial departments need sodium hydroxide. When used, the departments with more sodium hydroxide are the manufacturing of chemicals, followed by papermaking, aluminum smelting, tungsten smelting, rayon, artificial cotton and soap manufacturing.

另外，在生產(chǎn)染料、塑料、藥劑及有機中間體，舊橡膠的再生，制金屬鈉、水的電解以及無機鹽生產(chǎn)中，制取硼砂、鉻鹽、錳酸鹽、磷酸鹽等，也要使用時大量的燒堿。同時氫氧化鈉是生產(chǎn)聚碳酸酯、超級吸收質(zhì)聚合物、沸石、環(huán)氧樹脂、磷酸鈉、亞硫酸鈉和大量鈉鹽的重要原材料之一。

In addition, in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water and the production of inorganic salts, a large amount of caustic soda should also be used in the production of borax, chromium salt, manganate, phosphate, etc. At the same time, sodium hydroxide is one of the important raw materials for the production of polycarbonate, super absorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a large number of sodium salts.

固體氫氧化鈉裝入0.5毫米厚的鋼桶中嚴封，每桶凈重不超過100 公斤;塑料袋或二層牛皮紙袋外全開口或中開口鋼桶;螺紋口玻璃瓶、鐵蓋壓口玻璃瓶、塑料瓶或金屬桶(罐)外普通木箱;螺紋口玻璃瓶、塑料瓶或鍍錫薄鋼板桶(罐)外滿底板花格箱、纖維板箱或膠合板箱;鍍錫薄鋼板桶(罐)、金屬桶(罐)、塑料瓶或金屬軟管外瓦楞紙箱。包裝容器要完整、密封，有明顯的“腐蝕性物品”標志。 氫氧化鈉對玻璃制品有輕微的腐蝕性，兩者會生成硅酸鈉，使得玻璃儀器中的活塞黏著于儀器上。

The solid sodium hydroxide shall be put into a 0.5mm thick steel barrel and sealed tightly, and the net weight of each barrel shall not exceed 100kg; Full opening or medium opening steel drum outside plastic bag or two-layer kraft paper bag; Threaded glass bottles, iron capped pressure glass bottles, plastic bottles or ordinary wooden cases outside metal barrels (cans); Threaded glass bottles, plastic bottles or tinned sheet steel barrels (cans) are covered with bottom plate lattice boxes, fiberboard boxes or plywood boxes; Tinned steel sheet barrel (can), metal barrel (can), plastic bottle or metal hose outer corrugated box. The packaging container shall be complete and sealed with obvious signs of "corrosive goods". Sodium hydroxide is slightly corrosive to glass products. Both will produce sodium silicate, making the piston in the glass instrument stick to the instrument.

因此盛放氫氧化鈉溶液時不可以用玻璃瓶塞，否則可能會導(dǎo)致瓶蓋無法打開。鐵路運輸時，鋼桶包裝的可用敞車運輸。起運時包裝要完整，裝載應(yīng)穩(wěn)妥。運輸過程中要確保容器不泄漏、不倒塌、不墜落、不損壞，防潮防雨。如發(fā)現(xiàn)包裝容器發(fā)生銹蝕、破裂、孔洞、溶化淌水等現(xiàn)象時，應(yīng)立即更換包裝或及早發(fā)貨使用時，容器破損可用錫焊修補。

The bottle cap cannot be opened when the sodium hydroxide solution is put into the bottle, otherwise the bottle cap may not be opened. During railway transportation, the steel drum can be transported by gondola. The package shall be complete and the loading shall be stable at the time of shipment. During transportation, ensure that the container does not leak, collapse, fall, damage, moisture and rain. If the packaging container is found to be rusted, broken, porous, melted and dripping, the packaging shall be replaced immediately or shipped as soon as possible. When used, the damaged container can be repaired by tin welding.

儲存于陰涼、通風(fēng)的庫房。遠離火種、熱源。 密閉操作，加強通風(fēng)。操作人員必須經(jīng)過專門培訓(xùn)，嚴格遵守操作規(guī)程。建議操作人員佩戴自吸過濾式防塵口罩，戴化學(xué)防護眼鏡，穿防毒物滲透工作服，戴橡膠手套。避免產(chǎn)生粉塵。搬運時要輕裝輕卸，防止包裝及容器損壞。配備泄漏應(yīng)急處理設(shè)備。使用時或者搬運時操作者佩戴勞保用品。

Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. Closed operation and enhanced ventilation. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, anti poison penetration work clothes and rubber gloves. Avoid dust generation. The containers shall be handled with care to prevent damage. Equipped with leakage emergency treatment equipment. The operator shall wear labor protection articles during use or handling.
